Rita wants to buy a DVD for $24. The DVD is on Sale for )21.60. Rita said that the sale price is 10% off the original price. Is Rita's Statement reasonable?
It's close.
What is 10 % of 24?
2.4
To determine whether Rita's statement is reasonable, we can calculate the original price of the DVD and see if the sale price of $21.60 is indeed 10% off that amount.
Let's use algebra to find the original price. Let "x" represent the original price of the DVD.
According to Rita's statement, the sale price of $21.60 is 10% off the original price:
10% of x = $21.60
To find 10% of x, we can multiply x by 10% (which is equivalent to 0.10):
0.10x = $21.60
Now, we can solve for x by dividing both sides of the equation by 0.10:
x = $21.60 / 0.10
Calculating this:
x = $216
So, the original price of the DVD is $216.
Now let's check if the sale price of $21.60 is indeed 10% off the original price of $216:
10% of $216 = 0.10 * $216 = $21.60
Since $21.60 is indeed 10% off the original price of $216, Rita's statement is reasonable.
Therefore, Rita's statement is correct. The sale price of $21.60 is 10% off the original price of $216.
